For Fish a great sentence is like a great athletic performance. It is an example of something done supremely well, so well that it cannot be bettered. Other similar feats will come along, but only to stand alongside it. What exactly is done in such a performance? There is no single answer, indeed no finite answer since there is no limit to the things that can be done with words.
